Arsenal midfielder Mesut Ozil has committed his future to the Gunners after claiming that he is 'really happy' at the club.

The German international midfielder joined the north London club from Real Madrid in the summer of 2013 for a club-record fee and has been an important player for Arsene Wenger's team in the last couple of seasons.

Ozil has been criticised for his performances, with many believing that the midfielder has been lacklustre and uncommitted in realising his full potential with Arsenal.

After a brilliant start to his career at the Emirates Stadium, the former Real star suffered a dip in form in the second-half of his debut season, which prompted most of the criticism.

His second season at the club has been curtailed due to a knee injury that kept him out for most of the first part of the campaign, but he has returned and been a key player for Arsenal thus far, as they continue their quest for a place in the top four and a place in the final of the FA Cup.

With all the criticism, the midfielder has been linked with a move back to his homeland in the summer, but Ozil has made it clear that he sees his future with the Gunners and insists that he is enjoying playing for them in the Premier League.

"I played in the Bundesliga and at Real Madrid. But the English Premier League is the strongest league in the world. Opponents never give up. Even if we're 3-0 in front with Arsenal, the players never give up and fight until the very last second."

The 26-year-old midfielder has been impressive in terms of performance and fitness since his return from knee injury and has been one of the key players for the manager in recent weeks that has seen the north London club enter the final stretch of the season in fine form.

"I don't need to prove them anything. But it is correct that I have to work harder to reach my goals," the German midfielder continued.

"That's why I'm working as hard as I never worked before in my life. My body is more stable and I feel fresher. You need that in England," Ozil concluded.
